Study Population
The Western Australian Pregnancy Cohort Study commenced in 198916 in which 2968 women were serially recruited at or before the 18th week of gestation from the public antenatal clinic at King Edward Memorial Hospital (KEMH) and nearby private antenatal clinics in Perth, Western Australia. Approximately 100 women per month were enrolled for a total of 30 months commencing in May 1989 and finishing in November 1991. The criteria for enrollment were gestational age between 16 and 20 weeks,
Results
Of 2868 live births, 2611 (91%) children were available for follow-up at 3 years (13 children had since died, 124 children had been withdrawn, and 120 children [predominantly living overseas] were lost to follow-up). Complete data for all analyses were available for 1803 (69% [1803/2611]) children. Selected sociodemographic, prenatal, and perinatal characteristics of the Raine Study cohort at birth were compared with those in our study children. Between nonparticipants and participants the
Discussion
We have shown that independent of maternal socioeconomic, demographic, and biomedical characteristics, maternal prepregnancy overweight and obesity reduces breastfeeding duration at all time points up to 6 months following birth.
The findings from our study agree with those of a prospective Australian study that examined the perinatal effects of maternal BMI.21 Despite adjusting for the effects of mother’s age, occupation, and time of first breastfeed, the findings from their study showed that

2019, Journal of PediatricsCitation Excerpt :Our results on breastfeeding disparities associated with maternal race and ethnicity, age at delivery, obesity, and education level were consistent with results reported previously. Breastfeeding rates were lower in women who were black and Hispanic,11-16 younger ages,27,28 obese,13,17-26 and with less education.21,29,38 Although parity has been associated with breastfeeding in combination with older maternal age in Japanese women,27 there was little disparity associated with parity overall in this study.
